Bad Design
Look closely at the pic that shows the bottom button unbuttoned. You can see that there is a strip of fabric on the inside. It runs vertically up the strip where the holes are, up to the top button.. If you wear unbuttoned, the weight of that fabric causes the flap to bend & open up. Hard to explain. But if you wear it unbuttoned it looks ridiculous. The strip bends open, and you see this long strip of fabric. Not the wool. Pass on it & get one that does not have this strip of fabric
